If you exercise longer than an hour you should eat a healthy snack right before you with your workout to your body maintain blood glucose levels

False.

Explanation:

It is true to say that you should eat something healthy before training, but the purpose is not to raise your blood glucose level. Ideally, you provide your body with energy through easily digestible carbohydrates (which will help your body burn sugar and fat by providing lots of energy) and a protein (aids in muscle recovery and maintenance). In addition, before training you should avoid fiber as it hinders the absorption of carbohydrates and leaving you in energy during training should also avoid excess fat. Last but not least, you should drink plenty of water and start hydrated training.
